Windows 7: Lost network trust on 2003 windows domain

I'm running W7 Ultimate on a network w/ 2003 Windows domain. When I first added this computer to the domain, everything worked fine for about a month. Then one morning I came into the office, tried logging in and received a message that the computer has lost it's trust connect with the domain.

I logged into the server w/ the DC, reestablished the trust connection from the server side but the comp is still giving me the "Can't establish trust connection" error message when I logged in.

My current workaround is unplug the network cable, log into the comp then replug the network cable.

Fix: Log in as a local Administrator, and leave the domain, reboot, then log in and re-join the domain. Be sure to type the FQDN (fully qualified domain name) in the domain field.

This works on all machines I have encountered the problem on our netowrk. The problem seems isolated to Server 2003 domains and windows 7 machines. Additionally, I have only encountered this on laptops lately... My HP XW4550 workstation with win7 pro has not had the problem yet... (knock on wood).
